Background Embolization of the middle meningeal artery (MMA) has emerged as a potential treatment chronic subdural hematomas (CSDHs). Objective To evaluate impact on recurrence rate postsurgical embolization CSDH in patients with higher than average risk recurrence. Methods A monocentric retrospective study was performed retrospectively collected data. From March 2018 to December 2019, MMA proposed an adjunct postoperative after burr-hole surgery operated for recurrent or independent factor, including antiplatelet therapy, full anticoagulation coagulation disorder, hepatopathy, alcoholism. Patients who had undergone were compared historic group between 2016 and 2018, selected based same inclusion criteria. Results During period, 89 (with 74 unilateral 15 bilateral CSDHs) included underwent procedure, leading 91 out total 104 being embolized (88%). These 174 (138 36 CSDH) control group. One major procedure-related adverse event registered. Four (4%) required group, significantly less 24 (14%) (OR=0.28, 95% CI 0.07 0.86, p=0.02). Conclusions Postsurgical may reduce CSDHs factor
